I've done all the tricks in the book to get the most up to date radio, reset radio signals, etc. Fact of the matter is, Samsung decided to be cheap with their radios as usual. A friend of mine has an s4 on Verizon as well, and we both run into the same weak signals when our friends are getting pretty solid signal compared to ours.
And a friend of mine on AT&T has one and he too says the signal isn't so great either compared to some of his work colleagues on the same network with different model phones.
